FLYER SPINNING MEANS Filed July 6, 1939 4 Sheets-Sheet 4 my, me I ALBERT uAu T'ou'vz o rT Arronn EYS Patented Oct. 22, 1940 UNITED STATES PATENT OFFICE FLYER. SPINNING MEANS Albert Nau-Touron, Le Vesinet, France, assignor to Isaac Frenkel, Paris, France 14 Claims.

The present invention has for its object a process and means for passing the yarn for rotary spinning and twisting members. Said process and said means which are utilisable ina general manner and in particular on frames for spinning and twisting natural and artificial textiles, can also be usedfor cabling or a similar operation.

.The invention consists, in its main principle, in causing the yarn to pass, before it winds on the rotary spooling or similarimember, in such a manner that it is applied at least once on said member or on the yarn or thread already wound on the latter.

Practically, the application of the yarn' is ef- 7 l6 fected on a zone opposed to that on which the winding occurs.

In a form of construction utilising a spinning fiyer of the type described and illustrated in the French Patent No. 684,493 dated February '7, 1929,

goin the name of the applicant, said spinning fiyer has perforations or the like arranged in such a mannerthat the yarn after it frictionally passes on the outer wall of the spinning fiyer and before ,winding on the rotary spooling member, passes on the yarn already wound, with a certain amount of pressure, according to a convex line and then passes through the wall of the spinning fiyer and finally winds on said member.

The invention can be applied, not only to devices of the typecomprising a spinning fiyer, but also to systems having the same functions and in particular:

g (a) To fiyers the ends of which comprise, in

this case, blades each provided with two perfora- 5 tions for the passage of the yarn as previously indicated;

(b) To rotary ring travellers;

(c) To fixed ring travellers;

(d) To bowls, bells or similar members.

40 The perforations for the passage of the yarn in the spinning fiyer, flyers or the like can laterally open through a groove, slot or the like which is judiciously inclined for introducing or extracting the yarn, said perforations being located in one and the same plane or in difierent planes suitably spaced apart.

The rotary spooling member, such as a spindle or the like effecting on said member or on its bobbin the spooling action, can be "a driving member, the mentioned fiyer or the like effecting the twisting and the relative drag in angular speed for the spooling and exerting the tension on the yarn being simply braked.

Reversely, the flyer or the like effecting the twisting of the yarn can be a driving member,

- the spooling member such as a spindle or the like effecting the spooling and exerting a tension on the yarn being simply braked.

In the latter arrangement contemplated, it is possible to obtain, under correct conditions either 6 in function of the diameter which is variable of v the spooling, the braking of the spooling member by the action of the yarn passing on the wound part.

The control of the mentioned flyer or the like 10 can be applied to the prior systems.

. The invention also relates to an embodiment in which the parts of the fiyer, traveller, bowl, bell or the like, through which the yarn passes are made of metal resistant to wear, for instance, 1

of steel, the other parts being made of light metal or light metal alloy.

In a modification, not only the parts through which the yarn passes, but also the zones on which the yarn bears are made of metal resistant 20' to wear.

The parts made of hard metal are preferably encased upon casting in the light metal.

The invention also includes other particular points which will appear. in the following text giv- 25 en with reference to the accompanying drawings, by way of example only, in which:

Fig. 18 is a section, on an enlarged scale made according to line XVIII-XVIII of Fig. 16.

In the embodiment more particularly illustrated in Figs. 1 and 2, the yarn I, the balloon strand of which is indicated at I, engages in a spinning flyer 2 .through the perforation 3 opening laterally for allowing the said yarn to be placed in position or removed. It then passes, on a certain length and according to acertain are, on the outer peripheral part ofsaidTspinning flyer 2 and engages in a perforation 4 opening laterally. It then passes against the part. of ,the

yarn already wound on'thebobbin 5 andisubsequently passes through the wallet thespinning,

fiyer through a perforation Swhich opens lalt'erally. The yarn finally returnstowardsth e bob-,

bin andwinds on the latter by again passing" through the wall of the'spinning flyer through a" perforation I which can also open laterally. 3

In the example illustrated, the bobbin 5 which is a driving bobbin, rotates to the left in the dlrection of the arrow f (general case of twisting);

' the spinning fiyer being braked by'any/suitable meansv and in particular-by a yarn-drag 2 The yarn I follows the circuit indicated by'the successive arrows f f, f*, j 'and- ..-"A peripheral friction of the yarn I is thus obtained on the layers of yarnalready wound on the bobbin 5 This friction assists theyam'in its function for driving the spinning fiyer; and,,.the parts and members which are rigid therewith. Owing to this passage of the yarn, thenarrow and therefore diflicult passage'of the spooling points. 8 is rendered easier, so that it is possible to spin (or twist) finer yarns or to manufacture yarns of, less twist.

The location of the various peripheral holes 3', 4, 6 and l is suitably devised to function for the purpose to be attained. The holes 4 and 6 which determine the plane of mutual frictiomof the yarn, are arranged, in the example of Figs. 1 and 2, in a plane at right angles to the spindle.

Moreover, the hole I is located in this plane. The holes 4 and 6 can be located in a plane which is oblique relatively to the spindle, the hole 1 being arranged so that the spooling takes place, either in a zone located at a level higher or lower than that of the friction zone of the yarn, or at the same level as said friction zone. This system allows, by a judicious choice of the spooling level, of facilitating passing the point 8 and the neighbouring zone.

The passage of the yarn according to the invention prevents the vibrations of the bobbin and of the spindle owing to the opposite and balanced'actions oi the radial and opposed resultants generated by the tension of the yarn. Furthermore, a mutual smoothing of the yarn is obtained as it frictionally passes on the layers already wound.

For introducing the yarn l in the spinning flyer, use can be made, not only of the hole 3, but also of any one of the holes 3, 3 etc., so as to modify the value of the angle according to which the yarn embraces the spinning fiyer.

This conditioning of the tension of the yarn between the balloon strand I and the tangent winding strand 1 is effected before the yarn passes through the hole 4.

For the rotation of the bobbin 5 in the direcdriven member is the spinning flyer 2, the same members as those of Figs. 1 and 2 being designated by ."the same reference numerals in said tags. 3 and 4.

.The spinning fiyer rotating, for instance to the a right; according to thedirection of the arrow f (general case of spinning), the yarn l (balloon strand 1) successively engages in the holes 3, 4, 6 and 1. The same advantages are obtained as those previously indicated. However, in the first embodiment, the braking action must be exerted on thespinning fiyer whereas in this second em- Now, this braking of the bobbin is automatically obtained by the yarn frictionally passing on the wound layers. variable according to the very variations of the spooling diameter of the bobbin. Said variable braking can be suflicient, but it can be completed by a constant braking action.

The same particular remarks and arrangements indicated concerning Figs. 1 and 2 also apply to said second embodiment.

Figs. 5 to 8 illustrate an improved flyer devised according to the invention in view of obtaining the particular passage of the yarn I.

The yarn i, after partially winding on the branch ll] of the fiyer, passes through the hole H formed in a blade l2 and then engages in the holes 4 of the blade l2 and the holes 6' and 'l of a blade l4 terminating the other branch of the flyer. Said holes 4*, 5" and lit substantially correspond to the position of the holes 4, 6 and I of the two first embodiments and the same advantages indicated concerning the latter are obtained with the improved flyer which can also be reversed. a

A bracelet 50, made of metal or alloy and of suitable cross section, circular-pr not, is rigid with travellers 3 3 a, etc. or the like, suitably arranged on the bracelet 50. Said travellers are preferably rigid with the ring 5| so as to be stationary with the latter, said ring which is fixed in the form illustrated, having any suitable cross section. The yarn l (balloon strand I) coming from the drawing or dofilng cylinders, engages, according to the method above set forth, in any one of the travellers 3 3 a or a l: and preferably winds on the bracelet 50. After having passed through the traveller 4 the yarn I rubs on the bobbin 5, successively engages in the travellers Moreover, said friction action is.

6 1 and finally winds on the bobbin 5 which is a driving bobbin in the example illustrated.

The passage of the yarn l corresponds to a spinning operation, that is to say to a rotation of the bobbin 5 in the direction of the arrow 1", while the ring 5| and bracelet are stationary.

In an alternative form of the invention, the ring 5| and the bracelet 50 can be driven, the bobbin being braked.

Figs. 11 to 15 illustrate an embodiment in which a bar 2| is secured to the frame of a spinning device 22 by means ofarms 23. A ring 24,

'rotatively driven. The spindle 5 rotates and pivots on its pivotal rod 30 which is secured to the bed 3| having a reciprocating movement defined by the arrows 32. The spindle 5 spooling theyarn comprises a groove '33 and a drum 34.

. In the groove 33 acts. a braking element 35 secured at one end whereas the other end receives a dragging weight 36. Use can be made of rocking or sliding members 35 or any other suitable braking means (mechanical, electric, or the like).

Uprights 31 guide the beds 3|.

The yarn I, coming from the drawing'or feed-' ing system 39 passes on yarn-guide 40 and in a fixed or vertically movable ring 4 I.

The ring 4| can be replaced by two threads 42 (Figs. 12 and 13).; The ring 4| and the two threads 42 can moreover be done away with.

The ring 24 and its spinning flyer 2 can be devised for ensuring the passage of the bobbin, a brake allowing to stop the ring carrying the spinning flyer during the operation of the spinningframe.

The drum 34 serves to wind up a few under turns of the yarn which saves time upon the lifting operation and eliminates the readjusting operation.

The formation of the bobbins can be effected,

either in parallel layers (Fig; 14) or in conical layers as shown in different phases in Figs. 11, 12 and 13, or in any other manner.

The yarn coming from the yarn-guide 40, passes through the ring 4| or between the threads 42 and engages in one of the peripheral holes 3 of the spinning flyer 2. Said yarn externally rubs on the spinning flyer, passes in the hole 4 of the spinning flyer 2 and directly winds on the spindle or, according'to the arrangement indicated concerning Figs. 1 to 8, which arrangement is particularly applied to Fig. 11.

An arrangement reverse to that illustrated in Figs. 11 and 12 can be used for the spinning flyer 2. Said reversed arrangement is shown in Fig. 13 in which the spinning flyer 2 is reversed. The passage of the yarn is consequently reversed, the yarn passing throughthe bore of the ring 24 and of the spinning flyer 2 with all the necessary freedom and it issues externally through the hole 4 then through the chosen peripheral hole 3.. This arrangement allows of reducing the bore of the ring 24 and of the spinning flyer 2 and of obtaining thereby greater speeds and certain constructional facilities.

Instead of controlling the bobbin, the and consequently the spinning flyer 2 can be controlled.

The control of the driving members can be effected individually, in groups, or together and it is either mechanical (ropes, spindle cords, belts or the like) or electric.

It is obvious that the embodiments described and illustrated are given herein only by way of indication and not in a limiting sense. All modifications or changes which do not alter in any way the main features above set forth or the desired result, remain-included in the scope of the present invention.
